Measurements of LIBS spectra in an atmospheric pressure laboratory burner and pressurized sub-scale rocket combustion chamber are reported. LIBS is being developed as diagnostic for near wall measurements in liquid rocket combustion chambers as part of an AFRL effort to experimentally determine relative concentrations of major combustion species in rocket chambers and reduce validation uncertainty of CFD heat transfer tools. The potential for simultaneous use as a health-monitoring diagnostic i.e. detection of wall and injector erosion is also discussed.
